Using Neutron Stars to Probe Fundamental Physics
Tim Linden, The Ohio State University
Event Type: HEP Seminar
Time: 2:00 PM - 3:30 PM
Location: 726 Broadway, 940, CCPP Seminar
Abstract: Over the past few decades, terrestrial experiments have placed increasingly strong limits on the dark matter-nucleon scattering cross-section. However, a significant portion of the standard dark matter parameter space remains beyond our reach. Due to their extreme density and huge gravitational fields, neutron stars stand as optimal targets to probe dark matter-nucleon interactions. For example, over the last few years, the mere existence of Gyr-age neutron stars has placed strong limits on models of asymmetric dark matter. In this talk, I will discuss novel methods that utilize neutron stars to potentially detect dark matter interactions by studying the galactic morphology of neutron stars, as well as the electromagnetic signals that may be produced via neutron star collapse. Intriguingly, these observations can probe extremely generic dark matter models spanning from MeV - PeV energies, including troublesome portions of parameter space such as pure-Higgsino dark matter.
